Introduce Flow table test. How can sulphate attack be controlled?
Flow Table Test:-
This is a laboratory test, which gives an indication of the quality of concrete with respect to consistency, cohesiveness and the proneness to segregation. In this test, a standard mass of concrete is subjecting to jolting. The spread or the flow of the concrete is measured and this flow is related to workability.
Sulphate attack can be controlled by:
What are the initial and final setting times of cement ? How are they experimentally determined ?
